I would be interested to hear from anyone who has researched the neurological mechanics of how heat eases pain.

I ask because of my experience in a French hospital in 1980, when I was given an ice pack to relieve stomach cramps.

Pain is usually due to inflammation which generates its own heat, so the application of heat doesn't appear the logical thing to do.

I still prefer my Soothanol X2 which contains DMSO to enable the herbal ingredients to pass through skin direct to the source of the pain
